Hat Yai Tong Rod

For flood victims who need help fast and for the responders and agencies trying to coordinate aid in chaos. By moving help requests onto a simple map anyone can use from a phone, it connected people in danger to rescuers in real time and fed a single data picture to the government — at a scale (1,000,000+ concurrent) no offline call-centre could match.

A help-coordination web app built under emergency conditions during the catastrophic Hat Yai floods of late 2025 — a record 630 mm of rain in just 72 hours that affected over 3.5 million people across nine southern provinces. Victims simply open the site (no app install), sign in with Google, drop a pin, and specify what they need — number of people, food, medicine, or medical aid — plus a contact number, so rescue teams and Songkhla provincial agencies can see each request and respond. At peak the platform served more than 1,000,000 concurrent users, and request data was forwarded to Thailand’s Big Data Institute (BDI) to centralise the relief effort on behalf of the government. Built by a student from the Department of Mathematics & Computer Science, Faculty of Science, Chulalongkorn University.
